MACHINE FOR SANDING BRICKBMOLDS.

SPECIFCATIN forming part of Letters Patent No. 290,736, dated December25, 1833.

" Application led April 3, 1883. (No model.)

To rz-ZZ whom it may concern:

Be it known that I, WARRE BROWER, of Newburg, in the county of Orangeand State of New York, have invented a new and Improved Machine forSanding Brick-Molds, of which the following is a specification.

The molds used in brick-machines have to be sanded before the clay ispressed into them; and the object of my invention is to provide a simplemachine which shall be automatic in its action, and which will, afterapile of molds are placed one on another, feed them one by one into thesanding-machine proper, and deliver them at'ter sanding them.

My invention consists in novel features of construction and combinationsof parts hereinafter described, and pointed out in the claims, wherebythe desired result is attained.

In the accompanying draw-ings, Figure lis a plan of my improved machine.Fig. 2 is a transverse vertical section thereof on the plane of thedotted line m x, Fig. 1; and Fig. 3 is an end elevation thereof.

Similar letters of reference designate corresponding parts in all theiigures.

A designates a sand box or case, which may be of any suitable form, andconstructed of Wood or metal. It is provided on one side with a hopperor chute, A, through which sand may be introduced into it.

B designates a shaft journaled in suitable bearings in the box or caseA, and carrying a frame or reel, B, which may be of any desiredconstruction. and which isI secured fast to the shaft, so as to beturned with it. The rotary frame or reel B should be about'as long asthe brick-molds to be sanded, and itis provided on its perimeter orouter face with a number of slideways, C, of which three are here shown.These slideways extend lengthwise ofthe shaft B. They may be made of orlined with metal, and are of a size to permit the brick-molds D to beeasily slid intoV them, as shown in Figs. l and 2. rlhe slide- Ways areopen at the ends, so that the molds may be slid into one end thereof andshoved out the other end by the introduction of a second mold, and theyare of suoli construction that they hold the molds securely on the reel,independently of other means, as the reel rotates.

Placed intermediately between the slideways C are scoops E, which may bemade of sheet metal,with open mouths a.. The scoops may each be made ofa single piece of sheet metal, having portions b bent at right angles toform the ends ofthe scoop, and these ends may have in them slots c,through which may be inserted bolts c', thus providing for adjusting thescoop to increase or diminish the size of the mouth a. A continuousrotary motion or a step-by-step rotary motion may be imparted to thercel or frame B by any suitable mechanism. As here shown, F designates anotched or ratchet wheel, which is iiXed on the shaftB; and F designatesan arm' mounted loosely on said shaft, and adapted to be moved back andforth by a connecting-rod, d, reciprocated by a crank, d', on adriving-shaft, G. The arm F carries a pawl, e, and at eachhalfrevolution of said crank the reel or frame B is moved a fraction ofa revolution, so as to bring one of the slideways C uppermost at eachstep, and during the remaining half of the revolution the arm F is movedbackward, the pawl moving idly over the wheel F. The shaft G may berotated by a hand-crank, or in any other suitable way. This gives ampleopportunityr for removing the mold D from the top slideway, O, andintroducing another mold to be sanded. The molds D are inserted upsidedown in the slideways C, and the reel or frame B and shaft B should berotated in the direction indicated by the arrow in Fig. 2. The mouth aof each scoop will then dip into and take up sand in the box or case A,and as the scoop moves upward the sand runs or flows backward and ontoand into themoldin rear of the scoop. The molds are wetted be- .forebeing placed in the machine, and when theyreach the point where theywereinserted the sand falls out to be again scooped up, and sufficient sandis left adhering to the molds to serve the purpose intended. The moldsmight be inserted into and withdrawn from the slide- Ways C by hand, butpreferably I employ a feeder or feeding apparatus. (Shown in Figs. l and3.) y

H designates a slide way which extends from the box or case A, and isarranged so that after each partial revolution of the frame or reel B itwill stop with one of the slideways C opposite and in line with theslideway H.

ln the slideway H is a pusher or plunger, I,

reciprocated by a connecting-rod, J, from a crank, K. The crank K isjournaled in bearings j', and may be operated by means of bevelwheels gg from a driving-shaft, g. The shaft may be connected by suitablegearing with the shalt G, or it may be operated independently Themechanism should be so timed that the plunger or pusher I will make itsforward movement while the reel or frame B is stationary. lThe moldsDare placed in apile at the inner end of the slideway H, and as theplunger or pusher moves in it pushes the lowermost mold from theslideway H into the slideway C. thereby displacing the mold and forcingit out at the opposite side of the reel or frame B. After this thepusher I moves back entirely beyond the pile of molds D, and the moldsdescend so as to bring the lower one opposite or in the way of thepusher at its next movement. All that is necessary is to place the moldsin a pile on the feedingslideway H and to keep a supply of sand in thecase A. rEhe machine will then operate entirely automatically, and willsand molds expeditiously and at a small cost.

W hat I claim as my invention, and desire to secure by Letters Patent,is-

1. rIhe combination of asand box or case, a rotary reel or framejournaled therein, and provided with open-ended slideways extendinglengthwise on its iace, i'or the reception of molds, said slidcwaysbeing so constructed that molds may be slid into them from their ends,and that they will retain the molds independently of other means as thereel or. frame rotates, scoops arranged intermediately between saidslideways, for lifting the sand and filling the molds, and mechanism forimparting a rotary motion to said reel or frame, substantially as andfor the purpose described.

2. The combination of the sand-box A, the shaft B, the reel or frame B',comprising slideways C, the scoops E, arranged between the slideways,and having adjustable mouths, and mechanism for imparting a rotarymotion t0 said reel or frame, substantially as herein described.

3. The combination, withasand box or case, a mold reel or framejournaled therein, and comprising 'open-ended slideways, into the endsof which molds may be slid, and intervening scoops, and mechanism forimparting a step-by-step rotation to the reel or frame, o1" the slidewayarranged at the end of said reel or frame, and a reciprocating pusher orplunger working in said slideway, for feeding the molds into theslideways of said reel or rotary frame in the intervals between thestep-bystep movements ofthe latter, substantially as herein described.
